Biotechnological Applications of Purple Non Sulphur Phototrophic Bacteria: a Minireview
Bacteria play in vital role in the production of variety of products, including certain plastics and enzymes used in detergents, textiles and pharmaceutical industries. Production of chemicals using bacteria and other microorganisms is not only economical sustainable but also ecofriendly. Modern biotechnology entails the use of cell fusion, bioinformatics, genetic engineering, structure based m...
متن کاملDimethylsulphoxide reductase from purple phototrophic bacteria: structures and mechanism(s).
With the exception of nitrogenase, molybdenum is present in a diverse, but coherent group of enzymes which contain a pterin molybdenum cofactor (Moco) as a prosthetic group [l]. This group of enzymes, known as the molybdenum oxotransferases and hydroxylases, carry out a two-electron oxidation-reduction reaction which is linked to oxygen atom transfer to or from a substrate. This is illustrated ...
متن کاملBacteriocin from Purple Nonsulfur Phototrophic Bacteria, Rhodobacter capsulatus
To find whether productivity of bacteriocin is controlled between different species under unusual cultural conditions, we used Rhodobacter capsulatus ATCC 17016 as a producer and Rhodopseudomonas palustris ATCC 17003 as an indicator. Rhodobacter capsulatus was cultured under aerobic conditions in the dark in Lascelles medium containing 0.3% Triton X-100. As a result, bacteriocin productivity in...
متن کاملAnaerobic oxidation of ferrous iron by purple bacteria, a new type of phototrophic metabolism.
Anoxic iron-rich sediment samples that had been stored in the light showed development of brown, rusty patches. Subcultures in defined mineral media with ferrous iron (10 mmol/liter, mostly precipitated as FeCO3) yielded enrichments of anoxygenic phototrophic bacteria which used ferrous iron as the sole electron donor for photosynthesis. Two different types of purple bacteria, represented by st...
متن کاملCharacterization of phototrophic purple nonsulfur bacteria forming colored microbial mats in a swine wastewater ditch.
The community structure of pink-colored microbial mats naturally occurring in a swine wastewater ditch was studied by culture-independent biomarker and molecular methods as well as by conventional cultivation methods. The wastewater in the ditch contained acetate and propionate as the major carbon nutrients. Thin-section electron microscopy revealed that the microbial mats were dominated by rod...
